CATTLE-GUARD.

Specification of Letters Patent.

Patented Nov. 13, 1906.

To all whom it may concern:

Be it known that we, GUsTAF JOHNSON and JOHN JACKSON PINOKNEY, subjectsof the King of England, residing at Blaine, in the county of Whatcom andState of Washington, have invented a new and useful Cattle- Guard, ofwhich the following is a specification.

This invention relates to cattle-guards, and has for its object toprovide a simple, inexpensive, and efiicient device of this characterfor preventing the passage of cattle along or upon railway-tracks.

Afurther object of the invention is to provide improved means forelevating the pivoted guard or gate and means for preventing accidentalupward movement of the gateactuating platform when the latter is innormal position.

A still further object is to generally improve and simplify this classof devices, so as to add to their utility and durability, as well as toreduce the cost of manufacture.

With these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, and illustrated in the accompanying drawings, it beingunderstood that various changes in form, proportions, and assemblage ofparts may be resorted to within the scope of the appended claims.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan view of a cattle-guard constructed in accordancewith our invention. Fig. 2 is a transverse sectional view taken on theline 2 2 of Fig. 1. Fig. 3 is a longitudinal sectional view. Fig. 4 is adetail perspective view of one of the bearing-plates.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The improved cattle-guard may be formed of wood, metal, or othersuitable material and consists of an intermediate section 5, adapted torest upon the ties 6 between the rails 7, and the side sections 8 and 9,adapted to engage the ends of the ties on each side of the rails, saidsections being detachably secured together in any suitable manner, as bytie-plates 10, disposed beneath the rails, as shown.

The guard-sections are each formed of a pair of spaced parallel sidemembers or bars when the gates are in normal or lowered po- I sition.

Secured to the side bars at the pivoted end of each gate arebearing-plates 18, in which are journaled the trunnions 19 ofgate-actuating platforms 20. Fastened' in any suitable manner to thebottom of each latform is a wedge-shaped cross-beam 21, a apted toengage the extension 22 of the adjacent longitudinal beam 16 whentheplatform is depressed, and thereby elevate the gate, the end of theextension being inclined or beveled at 22 to correspond to the inclinedface of the cross-beam 21 as shown, and also to present a smoothbearing-surfaoe for engagement with the bottom of the platform.

By varying the angle ofthe inclined faces of the extensions 22 andwedge-shaped crossbeams 21 the pivotal movement or throw of the gatesmay be regulated at will.

The bearing-plates 18 are provided with angular extensions or arms 23,adapted to engage the tread-surfaces of the latforms when the latter arein normal position, so as to prevent accidental upward movement of saidplatforms.

As means for reventing the hoofs of the animal from we ging between theplatforms and the adjacent cross-tie 6 the ends of the side bars 11 areinclined or beveled and connected by cross-beams or guard-rails 24,having their inner faces Inclined or concaved, as

is removed from the platform, the gate will return to horizontal ornormal position by gravity and when in this position will present atread-surface having sharp exposed edges, so as to prevent the animalfrom walking upon the same.

Having thus described the invention, what is claimed is- 1.Acattle-guard comprising agate mounted for swinging movement andprovided with an extension, and a depressible platform normally disposedin a substantially horizontal plane and having its lower face at one endthereof inclined orbeveled and adapted to engage said extension formoving ,the gate to operative position.

2. A cattleguard comprising agate mounted for swinging movement androvided with an extension having its terminal portion inclined orbeveled, and a depressible platform normally disposed in a substantiallyhorizontal plane and having its lower face correspondingly inclined orbeveled and adapted to engage the beveled end of the extension formoving the gate to operative position.

3. A cattle-guard comprising spaced side rails, a gate pivotally mountedfor swinging movement between said rails, bearing-plates secured to therails and provided with angularly-disposed arms, and a depressibleplatform pivotally mounted in said bearingplates for moving the gate tooperative position, said arms being ada ted to limit the upward movementof the p atform.

4. A cattle-guard comprising spaced side rails, a gate pivotally mountedfor swinging movement between the side rails and consisting oftransverse bars having inclined recesses formed therein, longitudinalbars seated in said recesses, bearing-plates secured to the rails, adepressible platform pivotally mounted in said bearing-plates for movingthe gate to operative position, and an inclined rail connecting the endsof the side rails at the free end of the platform and extending belowthe latter.

5. A cattle-guard comprising spaced side rails, a gate pivotally mountedfor swinging movement between the side rails and con sisting oftransverse bars connected by longitudinal bars one of which is extendedbeyond the end of the gate, and a depressible plat form pivoted betweenthe side rails and having its lower face inclined or beveled and adaptedto engage the extension for moving the gate to operative position.

In testimony that we claim the foregoing as our own we have heretoaflixed our signatures in the presence of two witnesses.
